COOLING SYSTEM FOR HOUSES OR ROOMS.

Application and september 24, 1921. serial No.`5o2\,917.

To all rfa/1,0m it may concern.'

Be it known that I, LEWIS A. GOODWIN, a citizen of the United States, residing at Cora, in the county of Sullivan and State of Missouri, have invented certain new and useful Improvements in Cooling Systems for Houses or Rooms, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to systems for causing cool air to be discharged into rooms of houses, and more particularly to means of this character in which the cool air is taken from an underground chamber so that the air is cooled not by ice or like means but by the natural coolness of the earth.

The general object of the invention is to provide acooling' system of this character which is very simple, vwhich may be therefore cheaply installed, and which is thoroughly effective.

yAnother object is to provide means whereby the air may be drawn positively into the chamber within which the air is cooled and forced into the several rooms, means being also provided whereby the discharge of air into the several rooms may be controlled.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a diagrammatic sectional view of building having my improved cooling means applied thereto;

Figure 2 is a fragmentary sectional view showing a slight modification;

Figure 3 is a diagrammatic view of the building with my cooling system applied thereto.

In these drawings, it will be understood) that I have illustrated my system diagrammatically and that the details of the parts and their arrangement will depend largely upon the building to which the cooling system is to be applied. In Figure 1 I have illustrated my cooling System as applied to' a house having a number of rooms A. Exterior of the house or in any desired location there is formed a chamber 10 which is disposed preferably beneath the ground'. This chamber as illustrated is to be vlined with concrete 11 or 'with brick or conin any suitable manner. The

chamber 10 when and where a double conductor is used constitutes a chamber for air, and may be partly or entirely filled with water. Entering this chamber is an intake pipe 12 which may be provided with a cap 13 at its inlet and which would prevent the entrancev of rain but permit the entrance of air, this pipe 12 extending to or near the lower end of the cooling chamber or pit 10 and then extending upward through this chamber, as at 12a, nearly to the upper end thereof and then extending out of this chamber at an inclination and extendin to a point beneath or to the side of one o the rooms and then upward through the first room of the series, being connected at its upper end preferably to a combined suction and blast fan ,14.- This fan may be propelled in any suitable manner and from the casing of this fan extends a pipe 15. This pipe may open directly into the room. From the pipe 15 extends a pipe 16 which extend-s into the other rooms of the building or apartment, this pi-pe 16 being provided with, downwardly extending branches 17 discharging cool airfinto the upper portion of the room. y

The outlets from the pipe 16 may be arranged in any suitable manner and these outlets are preferably provided with capsv 18 which may be adjusted when desired to permit or prevent theventrance of air. Ob viously valves or diampers may be used for the same purpose. pipe 19 is arranged to open from the lower portion of any one or all of the rooms, this return pipe preferably extending into the chamber 10 at the upper portion thereof and being operatively connected to the vertical intake pipe 12 so that this warm air which escapes from the room is carried back into the pipes 12 and circulated through the pipe 12 and 12a back into the rooms along `with air which may be drawn from the exterior of this chamber 10. The pipe 19 within the room is provided with an extension on which a cap 13a is mounted. This extension may be made in various lengths according to the size of the roomV and also ltopermit the 'capped end of said suction pipe to be so positioned as to best remo-ve the warm air.

"Vhen the cap l13 is closed the conductor pipe 12 will then serve to supplyyair en- Preferably a return are thesame in all cases.

tirely from the exterior. One or both of the caps 13 and 13 may be partially closed.

It is obvious that the present invention may be used in cold weather, to raise or equalize the temperature in the rooms, as the temperature of the earth will be higher than that of the outs-ide air. The connected pipes 12 and 12a in Figure 1 rest upon suitable supports 12C. Furthermore the pipe or conductor 12 may be Hat-tened at any suitable location or to any extent, as shown at 12k. Also the lower end of 12n in Figure 1 may be disconnected from 12, as shown in Figure 2, thereby converting into a single conductor rather than a double conductor. I do not wish to be limited to the use of the inlet pipe 12, as the pipe section 12a may extend from the fan 111 down to the bottom of the chamber 1() andi take its air from there, the upper end of this chamber lObeing in that case open.

In Figure 2, I show a construction wherein the pipe 12X is the equivalent of the pipe 12. In Figure 2, I have illustrated the fan 14.4 as being upon the exterior of the house instead of the interior thereof and the pipe 12a as extending upward from the ground at or near the exterior of the wall of the house.

In Figure 2 an air inlet pipe 19L is shown as extending from the air chamber 10 to one of the rooms A, to conduct the air from the air chamber 10, or from the exterior thereof, to one of the rooms A. If desired, either of the caps 13 or 13a in Figure 2 may be Iremoved, to allow air to enter the chamber 10 from the exterior. Also, in Figure 2 the pipes ,12a and 12X are disconnected as shown and are supported in position by any suitable supports, such as 12h.

Preferably each of the discharge outlets or branches 17 will be provided with a cap 18 inthe form of a cone-shaped member having braces attached to a collar 18a. This collar may have screw-threaded engagement with the pipe 17 or otherwise arranged so as to permit this cone-shaped member to be shifted toward or from the mouth of the pipe to thus control the distribution of air. Of course, the cone-shaped member has a central portion 18b larger than the aperture, of the discharge branch, so that the cone-shaped member may be screwed home to closethe outlet from the branch 17.

It will be noted that in all the forms of my invention the air chambers are the same, the difference being that in one case I use a single suction tube drawing air from near the bottom of the chamber, and in the other case the double suction tube which draws the air from a point above the ground or from a room, and draws it through the air chamber, The dischargesfrom the pipe 16 The air chamber may be Vdug in the ground or a well or cellar may be used for the air chamber, and obviously in the latter case a pump may be used to withdraw any water which may collect in the air chamber. The air chamber may be walled or cemented, sides yand bottom, and covered on top. Any number of air chambers may-beused about a barn or house or in places where cooling is desired. I do not wish to be limited to the particular fan for moving the air as it may be of any size or type. It may be run by electricity, wind mill, hand, or any other suitable power.

In Figure 8 I illustrate diagrammatically that thepipe leading from the chamber 10 may extend underground around the house before entering the house instead of extending directly into the house, as in Figures 1 and 2. This pipe I have designated 12d to distinguish it from the pipes 12a which enter the house directly, but it will be understood that it is to all intents and purposes the.

same pipe.

It will be obvious that the conducting pipe 12, particularly if out of doors, as in Figure 1, may be insulated by suitable packing material. An air pump may be used in place of the fan for withdrawing the air from the pipe 12l when ejecting it into the rooms of the house. I do not wish to be limited to the use of a chamber such as 10 filled with ai'r cooled by contact with thel ground,k as thisr in the length of the pipe and inward of said discharge end of the pipe for` positively drawing air through the pipe from they intake end thereof and discharging itV out through said discharge openings, a pipesection leading downward into said underground chamber and having an inletopening above the ground, and a pipe leading from' said .building adjacent the floor thereof, exe tending into the upper end of the under-A ground chamber and discharging into said second named pipe adjacent the inlet end,
